This book talks about sustainable urbanization as the key consideration in environmental planning and management to improve living conditions for the 2.5 billion poor in the world. It examines policies and actions that might provide new, more effective responses to poverty, social justice, environmental degradation and other challenges as humans increasingly congregate in urban agglomerations. It also examines the experiences how the private sector and civil society can contribute to achieving sustainable urbanization. The book contains views of representatives of cities from all over the world in dealing with sustainable urbanization and information communication technologies.
